Wheelchair occupant restraint systems (WORS) are commonly installed in motor vehicels for individuals who do not transfer from their wheelchair into a motor vehicle seat when using transport. WORS existing of upper torso and/or pelvic belts are ususally installed fixed to the motor vehicle structure according to SAE J2249 belt fit criteria for a 50th percentile male occupant. However, when a fixed vehicle mounted wheelchair occupant restraint system (FWORS) is used to secure various sized wheelchair occupants, belt fit may be compromised resulting in user discomfort and unsafe conditions during motor vehicle impact. In the study a comparision was made between a FWORS and a wheelchair integrated occupant restraint system (WIRS). Belt loads of both restraint scenarios were measured during a 10 g/30 mph sled impact test of a wheelchair and seated Hybrid III test dummy secured with one of the occupant restraint scenarios. Results from the sled impact test showed higher wheelchair rear tie-down loads and lower upper torso and pelvic restraint loads for the WIRS scenario. The use of such a ''customiized'' WIRS could potentially decrease wheelchair occupant risk of injury and improve user comfort when compared to WORS, which are fixed to the motor vehicle.
